Ok, so I successfully converted my History textbook, but this happened.

Normal:

After Conversion:

So it went from 480 pages to 8500 pages. It made all the text huge! I do see an option for "Disable Font Size Rescaling" in the conversion "Look & Feel" tab. I was wanting to know if this would fix it. I would try it out, but it took like 750 minutes to complete the conversion last time, and I was surprised my laptop didn't die once while doing it. So I wanna make sure I know how to fix it before trying again.

You don't want to do that. azw4 is PDF, just in a Amazon wrapper. Converting PDF to PDF in calibre takes it through an intermediate XHTML stage. Not what you want at all.

Get the KindleUnpack plugin. Unpack the azw4. That will extract the PDF that's in the azw4 for you, with minimal changes. (Theoretically, zero changes, but the Kindle PDF renderer might work a little bit differently to whatever one you use with the extracted PDF.)

Ok, I will try that. Thanks guys!

EDIT: Using that Kindle Unpack Plugin worked! And it was almost instant haha. Ugh...
